13 plays 0In our laboratory, soil texture (fine sand, silt and clay) can be analysed using sedimentometry with the Sedigraph instrument. Spectrophotometers are used for plant…
-
6 plays 0The analyses of burning residues via BPCAs and plant pigments can be done after extraction and purification via our HPLC systems that have specific setups for these…
-
10 plays 0This laboratory fulfills a lot of different demands to freeze-dry samples as well as preparation of samples for texture analyses by ultrasonic dispersion. Further, we…
-
4 plays 0The organic geochemical analyses of samples requires proper preparation of extracts and separates of samples, which is done in dedicated laboratories, before gas or…
-
7 plays 0The samples that are produced in the MICE facilities are enriched in specific stable isotopes. To avoid cross-contamination with natural abundance stable isotope…
-
7 plays 0There are multiple devices that can be used in the laboratory and during field work. In this podcasts you see just three devices that can be used for different purposes…
-
6 plays 0Adequate field equipment is the base for highly sophisticated laboratory analyses. Therefore, we have several options to prepare soil profiles or we can also collect…
-
10 plays 0Specifically, within our laboratory classes we analyse soils for their nutrient composition which requires extraction of the nutrients followed by reflectometric…
-
10 plays 0Several types of analyses are necessary to characterize the mineralogical and chemical composition of soil samples. For this purpose, we perform the analyses or diffused…
-
2 plays 0One specialty of our laboratories is the preparation of samples for the natural abundance analyses of different radionuclides. In this laboratory, we prepare samples for…
-
1 plays 0One specialty of our laboratories is the preparation of samples for the natural abundance analyses of different radionuclides. In this laboratory, we have one fume hood…
-
8 plays 0We use our largest laboratory for sample preparation and the analyses of inorganic geochemical as well as physical soil and sediment properties such as grain size…
-
3 plays 0In this weighing room we have one analytical and one microscale to weigh in, e.g., standard materials for different purposes.
-
5 plays 0One of our two weighing rooms equipped with two analytical scales for high precision weighing. In the other laboratories, we have multiple scales for weighing in…
-
3 plays 0We can sieve, mill or break down rock, soil and plant samples within this laboratory in the basement of our building. As this room is located close to the sample archive…
-
4 plays 0The two self-made climate chambers are entirely computer-controlled and enable the manipulation of temperature, moisture, light, gas composition and further enable the…
-
4 plays 0On top of the characterization of bulk isotope compositions in samples, we are interested in the stable isotope composition mainly of hydrogen and carbon in different…
-
2 plays 0In this more specific podcast the sample preparation and analyses are described in more detail than in podcast 1.
-
7 plays 0Carbon and nitrogen concentrations as well as their stable isotope compositions are measured in the combination of our Flash HT Plus elemental analyser that is connected…
-
1 plays 0Sample storage is a very important issue to preserve unique samples or special samples that can be used for follow-up experiments or projects. Depending on samples and…
